Be kit known that 'LWVLLARD A.r SULLIVAN, acitijzen of the''United'Sttes` and residing at Jarnaiem' QI., fvinffthe county of ,Queens 'm11d`StLt'e of New York, "have invented cerf :tfain' new -and iisfeful Improvements' in 'Lock Wedge Devices, 'of `which'the following 'is' la specifiction, "such ifa-s,v Will Venable tliose skilledin thejrt yto fvvhieh it appert'ains to `nin-lieandnsethe-sttrne.

Ity vvill be noted thatfthepend14r` E'intlie construction shown, is` "fashioned 'frorn L a in form and these parts redeptedftoric# tiona'll'y enter the 'aperture'y 13 v'whereby the lpavvl Will` benetined .indifferentA positions j in ing.

It will be understood that the separate parts l0 and 1l are only Vcoupled together by4 placing one upon the other and interlocking the ribs with the channels of the respective parts to permit of the sliding movement of the parts one upon the other or the movement of onev part on the other part. In the use of the device, the separate parts l() and 1l are placed one lupon the other with the wide end `of oney part adjacent the narrow or contracted end of the other part and said parts-so coupled together are placed between two bodies or walls of bodies, for example the ybodies 1S and 19 asseen in Fig. lof the drawing, which partially represent a printing form, and type or printing matter in ythe form, and in .securing the bodies in proper posi- `tion to 'retain the same against displacement, the parts l0 and 11 are adjusted longitudinally by a. suitable tool as hereinbefore set out and when in proper position of adjustment, the pawl lli is moved intofengagement with one the teeth l2 to retain the parts in the desired position of adjustment,

it being understood that with the construction shown in Fig. 5 of the` drawing, the pawl 14 is automatically moved into operative position by the spring 17.v

Ihenit is desiredr to remove rthe wedge vdevice'or the separateparts i() and ll thereof, the pawl isreleased from the teeth l2 and the parts l0 and ,il moved into position to permit offtheirr removal fromY predetermined bodies or supports.`

I am Well aware of the fact that wedge relates are old in the art but in the use of such devices that'are now known, it has been found, invnractice, that theseparate parts of the wedge slip and become lloose, causing the displacement or shifting of the parts or bodies to be .secured and retained,

in position bysuch wedge` devicefthus Y rendering the wedge devices now infuse, im-

practical andV unreliable. With my improved construction however, .theobjections to devices of the class specified as now used, are lovercome in the provision of means for locking the separate parts 10 and li. of theA wedge ydevice against"` longitudinal movevment one upon the other whenin fiXed position of adjustment. Y

It will be understood that while I have i shown certain'details of construction for carrying my invention into e'ect that I' am not necessarily limited to the si'iecific structure herein shown and described, and vari-v ous changes therein and modifications there- Y of may be made within the scope of the appended claims without. departing from the spirit of my invention or sacrificing its a'ivantages.

`Having fully described my invention, what I claim as new and desire to sec-ure by Letters Patent, is

1. 'A' device of the 'class described comprising two wedge-shaped bodies adapted to be placed one upon the other, means for rei frictionally engage 'the body in connection with'which it is mounted to `retain 'the'pawl in predetermined positions.

2. A device ofthe class described comprising two interengaging and cooperative parts movable longitudinally of veach other, means on said parts for moving the saine longitudinally of each other',y one of said parts being provided with longitudinally spaced teeth and the other ofsaid parts being slotted at one enol thereof, a;

pawl pivotally mounted to said last named part and positioned withinsaid slot, said pawl being composed of sheet metal-folded to form two similar and spaced side portions having spring properties whereby th-e side portions of said pawl will fricti'onally engage the walls of the slot to retain the pawl in predetermined positions and said pawl cooperating with the teethof the other part for locking the separate parts against movement in one direction.

3. VIn a printers quoin of the class described, means for retaining'the separate parts of the quoin against movement in one direction comprising teeth arranged longitudinally-of the Vcontracted end portion of one part and a pawl pivotally mounted within a slot on the enlarged end portion of the-other part and adapted to cooperate withl the teeth of the first named part,l said pawl being'composed of sheet metal fashioned to form two similarly formed and spaced sid-e' portions'havingparts forengagement with said. teeth and finger parts, and means oooperatingwithfsaid -pawl for retaining the same in ypredetermined position. i
